Definitions
- This invention relates to a device for angularly adjusting the rolls forming part of finishing stands of a rolling mill equipped for the production of ribbed or threaded bars, or bars comprising special projections at constant pitch and/or at predetermined distances along the bar.
- the finishing stands of a rolling mill for producing bars comprising special essentially transverse ribs or profiles or for producing threaded bars are provided with rolls, the surface of which comprises notches or profiles repeated at constant pitch along the entire roll circumference.
- the pair of rolls must be set angularly relative to each other in a special manner so as to exactly position the grooves provided in the two rolls in the manner required by the type of rolling operation.
- One object of the present invention is to provide an angular adjustment device for the rolls which enables rapid action to be taken in correcting phasing errors between the stand rolls.
- a further object is to make said adjustment without dismantling stand components or disconnecting couplings or spindles.
- a rolling stand in particular with a pair of finishing rolls having essentially radial projections or notches inside the grooves of the sized passes, characterised by comprising a device for angularly adjusting an upper roll and a lower roll with respect to each other without disconnecting and removing the motion transmission means.
- FIG. 1 is an elevational view of a rolling stand with an angular adjustment device of the invention on the upper spindle;
- FIG. 2 is a cross-section through the rolls
- FIG. 3 is a partly sectional view of a spindle provided with a device according to the present invention.
- FIG. 4 is a view equivalent to that of FIG. 3 but with a different type of coupling
- FIG. 5 is an elevational view of a rolling stand with the adjustment device inside the pinion housing.
- FIG. 6 is a sectional detail of the pinion housing of FIG. 5.
- a roll housing 10 essentially comprises an upper roll 11 and a lower roll 12 which are connected by two spindles 13 to a pinion housing 14, which obtains its motion from a drive unit 15.
- the rolls 11 and 12 each comprise mutually facing grooves defining sized passes (not shown) and provided along their circumference with a series of essentially radial notches 16 shown diagrammatically in the sectional view of FIG. 2 and disposed at a distance apart such as to form an angle ⁇ at the centre. It is apparent that the maximum angle by which a notch 16 on the roll 11 and the corresponding notch 16 on the roll 12 can be out of phase is ⁇ /2.
- the upper spindle 13 is provided with an adjustment device constructed in accordance with the present invention and indicated overall by 17.
- the spindle 13 shown in FIG. 3 is provided at its ends with universal couplings 18, whereas the spindle 13 of FIG. 4 comprises toothed couplings 19, but these do not modify the operation of the device 17.
- Each of the two devices 17 comprises a sleeve 20 provided internally with a splined portion 21 and externally with a thread 22 at one end, this end being enlarged, and with helical toothing 23 at the other end.
- a locking ring 24 and a ring nut 25 which is secured in a freely rotatable manner at 26 to a portion 27 of a universal coupling 18 or to an inner portion 28 of a toothed coupling 19, both said portions 27 and 28 comprising internally a bore which is toothed in a complementary manner to the helical toothing 23.
- An end portion of the shaft 29 of the spindle 13 is splined in a complementary manner to the inner part of the sleeve 20.
- the sleeve 20 On rotating the ring nut 25, which is locked in a freely rotatable manner at 26 to a portion 27 and/or 28 of the couplings 18 or 19, the sleeve 20 is made to advance axially by virtue of the complementary threads 22.
- FIGS. 5 and 6 A further example of an adjustment device according to the present invention is shown in FIGS. 5 and 6.
- said adjustment device indicated overall by 30, has been inserted into a pinion housing 14 and is operated from the outside thereof by means of a control handwheel 31.
- Said handwheel 31 operates a worm 32 rigid therewith and engaging a complementary toothed wheel 33.
- the toothed wheel 33 of annular cross-section, comprises internally a thread 34 which engages a complementary threaded portion of a sleeve 35 containing the bearing of the upper pinion 36 mounted to the shaft portion of upper pinion 36.
- a key 37 is positioned between the load-bearing structure and sleeve 35 to prevent rotation of said sleeve 35, while at the same time allowing it to move freely in an axial direction.
- the worm 32 is rotated with consequent rotation of the toothed wheel 33. Said movement also causes rotation of the thread 34 and mutual sliding of the complementary thread 34 provided on the sleeve 35, thus causing this latter to move axially with consequent axial movement of the upper pinion 36.
- toothed couplings 19 on the spindle 13 does not hinder this. Rather, the reciprocal axial movement provided by toothed coupling 19 between upper pinion 36, specifically the shaft of upper pinion 36, and spindle 13 permits axial movement of pinion 36 without causing corresponding axial movement of upper spindle 13 and roll 11.
